(4) Real-time output port control register 0 (RTPC00)
Note
This register is used to set the operation mode, output trigger and operation enable/disable of the real-time
output port.
The output is RTP0 to RTP7.
The relationship between the operation mode of the real-time output port and output trigger is as shown in
Table 10-4.
RTPC00 is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears this register to 00H.
When RTPM00n (bit n (n = 0 to 7) of real-time output port mode register 0 (RTPM00)) is 1, INV0 (bit 4 of
DC control register 0 (DCCTL0)) is 0, and real-time output operation is disabled (RTPOE00 = 0), RTP0
to RTP7 output “0”.
